Fig'. 22 is a sectional rear view showingsevei'al trains in the total- 6 5 izer, which trains will be hereinafterdesignated as carrying-trains. Fig. 23 is a detail diagrammatic viewillusti'ating iiiy improved carrying' mechanism.

The machine shown in the accompanying' 7o drawings is of that typewherein the items ai'e set up on a keyboard, the keys of which cooperatewith stops to adjust control-bars in one of nine different positions,depending' upon the location of the key struck. The keys beforeoperating a control-bar cause a segmental gear on the said bar toengagea ti'ain which is connected to and opei'ates printing andindicating wheels. Before this ti'ain is restored to normal position thesegmental 8O gear is disengaged therefrom and a totalizei' may be throwninto engagement with the itemwheels, whereby the restoration of saiditemwheels operates to place the item in the totalizer. The totalizer iscomposed of sevei'al 35 carrying-trains and may be engaged with theitem-wlieels to drive the latter' to exhibit the total of itemsaccumulated in the totalizcr. The item-wheels ai'e self-clearing. Thetotalizer may be cleared or returned to zero at will.

In the following description I have employed headings, under which willbe found appropriate references to the pai'ts identified with therespective headings. 9 5

lVhile I have shown but one form of my invention in the accompanyingdrawings, it is obvious that many minor changes in the construction,arrangement, and combination of the several parts can be made andsubstituted for those herein' shown and described without in the leastdeparting from the nature and principle of my invention.

T/L@ keg/oawThe keyboard (see Figs. 1 and 9 to 12) consists of a numberof longitudinal series of keys running from l to 9,7 said keys havingusual button heads and shanks, the latter being guided vertically byplates 4 and 8. These plates are carried by posts 2, rising from thebase-framing' of the machine. Cross-tie bars 3 connect the upper ends ofthe forward posts and support the forward edge of plate 4, while crossframes or bars 7 are arranged between said posts, to the lower edges ofwhich are secured the plate 8. Plates 4 and 8 are providedwith suitableopenings 5 and 9, respectively, through which pass and are guided thekeyshanks.

10 represents springs connected to the plate 4 and to pins 11 on thekey-Shanks for elevating said shanks. As usual, the keys areindependently operable, and each series of keys has a control-bar commonto it whereby the depression of any key of a series will actuate the barcommon to that series in such manner that said bar will be moved to oneof nine different positions, depending upon the relative location of thekey struck. These controlbars, as I have termed them, (indicated at 14in the drawings,) are pivoted upon a shaft 13, mounted in the sideframes 12 at the back of the machine, said bars being spaced apart bywashers 15. Each bar is held in an elevated position by a spring' 16,and each bar carries at its rear end a segmental gear extension 17.These bars 14 have rearwardly-inclined slots 18 in their upper edgesopposite 4the key-Shanks, which at this point carry pivoted blocks 19,designed to engage iiXed abutments, in this instance the plate 4, toarrest the upward movement of the key-Shanks. Blocks 19 carryprojections or pins 2O at their lower ends in vertical alinement withthe open ends of the inclined slots 18, whereby when any key isdepressed bar 14 is swung on its pivot until arrested at the limit ofits designed movement by adjustable stops 21, having heads 22 in thepath of the pins 20. By referring to Fig. 1 it will be observed that theadjustable heads have shouldered projections 22 on their upper ends,which in the operation of the device are designed to cooperate with thepins 20, said pins riding down the inner side faces of their cooperatingprojections 22. The purpose of this is to hold the pin 2O firmly in itsslot 18 when the key is depressed, and in this manner lock thecontrol-bar to the depressed key; otherwise the sudden depression of thekey might result in the overthrow of the controlbar due to the momentumgathered in its downward movement. From this it will be seen that thecontrol-bar is forced downward by the pin 2O on the gravitating blockengaging the bottom of its inclined slot 18, and before the pin 20' isstopped in its downward movement it passes along the inner face of theprojection 22, and thus prevents the gravit-ating block from rocking inone direction, the walls of the slot 18 preventing the block fromrocking in the other direction, and so the control-bar is locked to thekeyshank and is prevented from moving past the designed position. Blocks19 being pivotally mounted on the key-Shanks will, when the keys towhich they are pivoted are depressed, swing on their pivots by reason ofthe inclination of the slots 18. Thus the key has an initial downwardmovement or vertical play during the travel of pin 2O in slot 18, andthe bar 14 is not moved until the pin reaches the bottom of the slot.

The rear cross-bar 7 affords stops 23 for horizontally-sliding bars 24,arranged in j uxtaposition to the key-Shanks and on the opposite sidethereof with respect to the coperating control-bar 14. These bars 24have reduced portions 25 at their rear ends, provided with collars 48and pins 50. (See Fig. 8.) Bifurcated arms 47 on a rock-shaft 44 bearagainst the rear faces of collars 48, being yieldingly held thereagainstby means of a spring connected thereto and to the pins 50. ln thismanner the rearward movement of the bars 24 will positively rock theshaft 44 in one direction, while the forward or return movement of saidbars is effected by the means which yieldingly return the shaft 44 toits normal or home position.

It will be noted that the rock-shaft 40 is common to all of the bars 24aud that when any one of said bars is operated to rock said shaft thesprings which connect the bifurcated arms 47 with the normal bars 24 areplaced under tension. Thus if any other bar 24 is subsequently operatedits connected spring will tend to draw the same rearwardly.

I have before referred to an initial idle movement of the keys, and itis during this movement that the bars 24, common to the series in whichthe operated key is located, is moved rearwardly to rock the shaft 44.

Located under pins 29, projecting from the key-Shanks, areescapement-dogs 26, pivoted to the bars 24 at 27. The front edges ofthese escapement-dogs are provided with cam-faces y28, 28, and 28, thefirst mentioned being in the nature of a beveled Lipper end. The initialdownward movement of the key-shank (see Fig. 12) will cause its pin 29to strike the beveled edge 28 of the escapement-dog located immediatelytherebeneath (see Fig. 12a) and move the bar 24 rearwardly, (see Fig.121),) because the lower end of the escapement-pawl carries a pin 31,operating between two pins 30, projecting from the lower edge of the bar24,

IOO

and said pin 31 is in contact with the foremost of said pins 30. Thecam-face 28n is disposed vertically, so that when the pin rides downover this cam-face the bar 24 will be held in a stationary position byreason of the vertical movement of the pin. (See Fig'. 12.) Th en thepin passes onto the cam-face 28b below the pivot 27, as shown in Fig.12C, the dog will be rocked and the face 28h disposed vertically, sothat a continued downward movement of the pin results merely in sorocking the dog and holding the bar 24 rearwardly. The pin 31 will nowengage the rearmost pin 30, placing a spring 32, connected to pin 31 andto a pin 33 on the bar 24, under tension, which tension is directed topulling the lower end of dog 26 forwardly. The lower end of dog 26 isprovided with a stepped shoulder 35, opening rearwardly, and as the pin29 passes beneath the lower end of the dog it is received upon aprojection 36, and the spring draws the lower end of the dog over thepin 29, as shown by dotted lines in Fig. 121. The projection 36 issubstantially L-shaped, and the forward face of its horizontal memberlies in the vertical plane of the cam-face 28b when the pin 29 is ridingthereon, and consequently the pin 29 easily passes from the cam-face ofthe dog onto the fixed support 36. This insures the bar 24 being heldrearwardly until the key reaches its lowermost position, in which thedog is released, and when the key rises the pin 29 is permitted to passabove the projection 36 and behind the dog, as shown in Fig. 12d,allowing the bar 24 to be returned to its normal or forward positionbefore the controlbar 14 is released. By this construction it will benoted that the keys do not remain down after being' pressed, that therock-shaft 44 is first operated through the bar 24 before thecontrol-bar is moved, and that after vthe depression of the control-barthe bars 24 are released and the rock-shaft 44 is in readiness to returnto its home position before the control-bars can be restored. Brieflystated, the keys by contacting with their respective stops determine theposition of the control-bars and the throw of their connected segmentalgears 17, while the bars 24 effect an engagement between the segmentalgears and the item recording and indicating mechanism, whereby the saidmechanism is in position to be operated by the segmental gears beforethe latter are actuated, and said mechanism may be disengaged from saidsegmental gears immediatel y upon the completion of the movement of thesaid gears in one direction, (the forward.) The item mechanism referredto is normally out of mesh with the segmental gears.

Verme for eject/ag m engagement between t/w 15cm accordi/ng (mdaiderait/ing mechanism cmd z/e coai'oZ-/CWS.38 indicates a pivotshaftmounted in suitable bearings in the frame-plates 12, upon which shaft isarranged.

a swinging' frame composed of the side framepieces 39, which are spacedapart by suitable tie-bolts. Spring 40 (see Fig'. 11) is connected tothe swinging frame 21 to hold the same normally in an elevated position.An adjustable fixed stop 41, coperating with a projection 42 on theswinging frame, limits the upward movement of said frame.

43 indicates a pin or projection extending laterally from one of theframe-plates 39, being received in a slot 46 in an arm 45, fixed to therock-shaft 44. Thus when the rockshaft 44 is rocked by any of the bars24 the item mechanism carried by this swinging frame is caused toprimarily engage the segmental gears by reason of the depression of saidSwinging' frame through the instrumentalities just above mentioned.

tem-Zr/ucrs.-51 indicates a shaft carried by the swinging' frame-plates39, upon which are arranged what I term groups of driving mechanismscommon to each segmental gear 17, s aid mechanisms being provided withmeans whereby they yieldingly drive the item mechanism, and when a totalis being' taken said item-driving' wheels serve as yielding'intermediate gears. (See Fig'. 8.)

52 indicates a pinion loosely mounted on the shaft 51, which pinion isdesigned to mesh with the segmental gear 17 when the latter is in itsrearmost position, (before it is moved by the control-bar.) This pinionhas a gear 53 conjoined thereto. Gear 53 is fixed to a sleeve 54,mounted upon the shaft 51, upon which sleeve is loosely mounted a gear55, said gear being' connected with the sleeve by a torsionspring 57,carried in a drum 56. ln this manner the gear 55 may be rotatedindependently with respect to the primary gear 53, the torsion-spring'tending' at all times to restore the gear 55 to its normal relation tothe driving or primary gear 53. This relation between these two gearsi-s established by means of a pin 58, extending inwardly from the faceof primary gear 53 in the path of a pin 59 on the gear 55. y(See Figs.13 and 14.)

indicates a centering-wheel, in appearance resembling a stai', which isconjoined to the secondary gear 55. (See F ig'. 15.)

61 indicates a centering-pawl coperating with the V-shaped notches inthe centeringdisk 60. This pawl is mounted on a shaft 62, which has abearing in the frame-plates 12, suitable washers or sleeves beingemployed to properly space the centering-pawls apart. (See Figs. 5 and8.)

63 indicates a rod carrying springs 64, connected to tailpieces on thecentering-pawls to hold them yielding'ly against the centeringdisks 60.65 indicates a stop-bar coperating with the said tailpieces forrelieving the centering-disks of undue friction. (See Fig. 8.)

38 and spaced apart by appropriate washers oiusleeves 67, so as to beconstantly in mesh with the secondary gears 55.

68 and 69 are pins projecting from the faces of the gears 66 and inwhose path are located pins 70, fixed in the shaft 38, said pinsprotruding through circumferential slots 71 in the sleeves 67. (See Fig.3.) These pins normally engage the pins 68 and aline the gears 66. Thepins 7 0 cooperate with the pins 69 for the purpose of restoring thewheels 66 to normal position after they have been operated in placing anitem in the itein-wlieels. The restoration of the gears 66 is effectedby a backward rotation of the shaft 38, which is produced by mechanismhereinafter referred to. The pins 69 are circumferentially staggered onthe wheels 66, so as to form a spiral series, whereby no two adjacentwheels will be started back at the same time. This results in successiverestorations of the gears 66, commencing with the mechanism identifiedwith the column vof lowest orders. 4Thus the carrying is effected in thedifferent groups of mechanisms in successively-iiicreasing orders.

72 indicates shafts mounted in fraiiieplates 12 and upon which arearranged transmittingpinions 73, in mesh, respectively,with the severalgears 66.

-Y 74 indicates gears mounted upon shafts 38, with which mesh pinions 75 on the shafts 72, whereby1 the item indicating and recording` devicesmay be grouped close together. (See Figs. 2 and 5.) These trains ofgearing from the gears 66 to gears 74 are identified with the 'severalcolumns and are independently operable, 4being' controlled by thedifferent series of keys.

76 indicates a shaft preferably supported in one of the frame-plates l2above the shaft 38, and upon which shaft 76 are gears 77, meshing,respectively, with the gears 74.

78 indicates a shaftupon which are mounted gears 79, meshing,respectively, with the gears 77. These gears 79 have type-wheelsconjoined thereto, said wheels carrying on their peripheries printingcharacters from 1 to 9 and also 0, the latter normally occupying aposition in the priiiting-line.

I have not shown in this application any type-hammers or means fortaking an impression from the type in the printing-liiie; but it is myintention to use some approved construction for printing and recordingitems and totals from these printing-wheels.

81 indicates ashaft upon which are arranged gears meshing, respectively,with the gears 77, and to which gears 82 are conjoined indicating-disks83, forming sight-wheels for the operator. (See Fig. 8.) Thesesight-wheels indicate the amount of each item registered, and toeffectthis they areprovided with niiv. a merals from i) to 9, inclusive, ontheir peripheries.

There the machine is used to register, re-

cord, and add the amounts indicating sums of money, such as at piesentcurrent in the United States, the dimes and cents wheels are preferablyseparated from the units dollar-wheel in lieu of printing thedecimal-point.

[ivm-m 1c/mn ma Incl: 84 indicates ratchetwlieels conjoined to theseveral gears 7 7, respectively, with which ratchets cooperate pawls 86,mounted iixedly upon a shaft 85. Shaft 85 extends outwardly beyond theframe 12 on one side of the machine, where it cai'- ries a dependingrock-arm 87.

88 indicates a rock-arm extending upwardly from the outer end of shaft38. A pin 89 on the upper end of'arni 88 engages the arm 87, which rocksthe shaft 85 to di sengage the pawls from their ratchets whenever thearm 88 moves rearwardly.

90 indicates a pin on a downward extension of arni 88, which pin lits inslot 92 in the end of rock-arm 93, fixed to the shaft 44.

Shaft 85 is provided with apin 166, to which is connected a spring 165,having its other end connected to a pin 167, fixed in the frameplate 12,(see Fig. 51.) whereby the pawls 86 are normally held in engagement withthe ratcliets 84.

By the above construction all of the wheels 77 are released whenever anyof the bars 24 is in other than a honie position.

Resto/ving HL@ f/Lcm.-zindcctng and type fui/aafla- -93 indicates astud-shaft in one of the frame-plates 12, upon which is mounted asegmental gear 94, meshing with a pinion 95, arranged upon the outer endof shaft 38. (See Figs. 1" and 2.) A spring 96 holds this segmental gearin an elevated position. y depressing this segment shaft 38 is rotated,so as to cause its pins 7 O to pick up gears 66 by engaging their pins69 and return said gears and their trains connected therewith to anorinal position.

97 indicates a handle on the gear 94, by which said gear may beoperated. This gear 94 is also operable by a lever 98, whose hub portionis mounted upon the stud-sliaft 93. The segmental gear 94 is providedwith a pin or projection 99 for cooperating with the lever-liandle 98.Operatingthe handle 97 independently of lever-handle 98 will cause thetype and indicating wheels to be returned to Zero position withoutplacing' the items in the accumulating or totalizing mechanism. Thus theitem mechanism may be cleared in the event that a mistake is made, andtherefore the handle 97 might properly be termed a correction-liaiidle.

ricami/Mating zf/u; fm/is fri/nf t/m tot/liscia- By depressing thelever-handle 98 the segmental gear 94 is not only operated to restorethe gears 66 through their pins 69, but the return movement of saidgears being exactly proportional to their advance is utilized in drivingthe totaliZing-gears. A condition precedent to the restoration of thegears 66 through the segmental gear 94 to place the items in IOO IIOV

the totalizer is the engagement of the totaliZer-wheels with the gears66 through the primary gears 53, coupled to the secondary gears 55. Inorder to effect this engagement before the gears 66 start on theirreturn movement, the lever-handle 98 is notched in line with theprojection 99, so that its initial movement will be utilized ineffecting the aforesaid engagement prior tothe commencement of thereturn or backward movement of said wheels. This is accomplished bymeans of a cam-notch 101 in the hub 100 of lever 98, in which notchrests the projection 157 of a lever pivoted at 156, whose other member,1 55, is provided with a cam-face for cooperating with a pin 158 on theswinging' totaliZer-frame 104. (See Fig. 1.) This frame is pivoted inbearing-plates 105` and when the projection 157 is in the notch 101 thetotalizer is out of engagement with its drivers. Vhen the lever 98 isdepressed ,the frame 104 is rocked forward to engag'e the totalizer withits drivers, after which the lever 98 restores the gears 66 and placesthe item theretofore set up therein in the totalizer. This isaccomplished by the gear 66 in its backward rotation backwardly rotatingthe gear 55, and through the medium of the spring the gear 53 is alsocaused to rotate and by rotating the pinion 110 set up the item in theconnected totalizer-train. This reverse rotation of gear 66 and itsdriven train effects the restoration to Zero of said itemtrain and itsconnected parts and at the same time sets up the item in thetotalizer-train, leaving' the item in the totaliZer-train when the gear53 is thrown out of mesh with its pinion 110.

To hold the rocking frame 39 in an elevated position and preventengagement between pinions 52 and the segmental gears 17 during thisoperation of placing the item in the totalizer, I provide an adjustableprojection 158L on the frame 104, which is designed in the forwardposition of the frame to occupy a position under projection 159 on theframe 39. Likewise when the frame 39 is depressed to engage the pinions52 with the segmental gears 17 the projection 159 is located in the pathof the projection 158 and prevents the frame 104 from being rockedforward to engage the totaliZer-wheels with the primary gears 53.

153 indicates a stop on frame 104, which cooperates with adjustablestops 152 and 154 to limit the rocking movement of said frame.

Carri/11g zio arl/210022.25 raul/)2s of Mg/zer 0r- (Zuz106 indicatestie-bolts in the upper ends of frame-plates 104, which bolts or rodscarry downwardly-eXtending plates 107.

108 indicates a shaft journaled in the lower ends of the plates 107.(See Fig. 22.) These plates, in addition to supporting the shaft 108,form division-walls for groups of gearing, corresponding in position tothe drivinggroups on shaft 51.

109 indicates sleeves on one of the shafts 106 for spacing the plates107. and 22.)

Each group or train of wheels on the shaft 108 comprises a pinion 110,in alinement with the primary gear 53.

Referring now to Figs-16 to 21, inclusive, 111 is a disk conjoined topinion 110, said disk having preferably ten radially-disposed slots 112in its periphery. 113 indicates a companion disk, preferably providedwith ten angularly-arranged slots 114 in its periphery. In the normalposition of these disks the outer ends of the slots 112 and 114register'. This registration is normally established by means of aspring 114, whose ends are connected to the disks, respectively. A pin111Ll on disk 111 cooperates with a pin 113 on the companion disk toinsure registration of the slots. 115 indicates a pawl pivoted to theinner face of disk 111, the free or inner end of which carries a pin116, passing through an opening 117 in the companion disk, beyond whichit cooperates with a notched disk 120, said lastnamed disk beingpreferably provided with ten V-shaped notches `121. 118 is an extensionof the pawl 115, which cooperates with a pin 119 on the disk 113, whichpin holds the pawl in engagement with notched disk 120 and locks-saiddisk 120 to the disks 111 and 113. 122 is a notched disk conjoined tothe disk 120, both of said disks being fixed to a sleeve 123, whichcarries a gear 124 at its opposite end. 125 is a centering orstar-shaped disk, with which cooperates a pawl 126, pivoted on a shaft127.

From the above it will be seen that the disks 111, 113, 120, and 122,and the gear-wheel 124 are all locked together by the pawl 115 androtated collectively. However, when the disk 113 is rotatedindependently, so as to relieve the pawl 115 from the restraint of pin119, permitting the pawl to ride over the disk 120, said disk 120 andits connected centering-disk 122 and gear 124 are free to turn.

128 indicates a shaft mounted in thc frame 104, preferably below theshaft 108, and upon which are a series of sleeves 129, each of saidsleeves carrying a cam-disk 130 and a gearwheel 131, the former beingpreferably immediately under the notched disk 122, and the latter'inmesh with the gear 124 of the next adjacent train of lower order. Thecam-disk is provided with a groove 132 in its side face, which groove isessentially concentric, save fox` a fluctuation 133. This cam-disk alsocarries a radial projection 134, which is designed to cooperate with andadvance the distance of one step the disk 122 upon each revolution ofthe cam-disk. This advance of disk 122 dis- (See Figs. 8

places the pin 116 and causes it to enter a notch 121 in the rear of theone it formerly occupied. This circumferential displacement of disk 120is only possible when the disk 113 is circumferentiall y displaced tocarry the pin 119 away from the projection 118 on pawl 115 to releaseIOO IIO

siaidpawl. rIhis displacement of disk 113 is effected by means of abell-crank lever pivoted on a shaft 115,mounted in the frame-plates 104.This bell-crank lever consists of a member 136, carrying a pin 137,which rides in cam-groove 132, a hub portion in the form of a sleeve138, and a member 139, carrying a pin 140, designed to simultaneouslyenter the slots 112 and 114 whenever the member 136 is caused to dip byits pin entering the fluctuation in the cam-groove. (See Fig. 7.) Thedipping` motion of the bell-crank lever, the displace ment of the disk113, and the consequent release of the pawl are practically coincidentwith the engagement between the projection 134 on the cam-disk and thenotched disk 122, which notched disk is rotated one-tenth of arevolution. As soon as pin 116 is seated in its newly-found notch and assoon as the bellcrank lever passes beyond the fluctuation in thecam-groove thedisk 113 will be released from its displaced position, andthe spring 114L will restore said disk to lock the pawl andincidentall)7 the disks and gears 111, 113, 120, 122, and 124 until theyshall have made another revolution or rather nine-tenths of arevolution, the last tenth being' devoted tothe operations abovedescribed.

In Fig. 23 I have illustrated diagrammatically the carrying mechanism,and in order that the operation of the parts may be understood I willbriefly describe the construction shown in this ligure. The segment 17is shown in mesh with the gear 52 on the shaft 51; but it will beunderstood that in ordinary operation when the gear 53, conjoined to thegear 52, is in mesh with the gear 110 on shaft 108 the segment 17 is outof mesh with the gear 52. I have shown segment 17 in the figure merelyfor the sake of locating' it with relation to the gear 52. I have notshown the companion transmitting-gear 55, as the same would obscure theview. Assuming that motion is transmitted through gear 53 to the gear110, the notched disks will be rotated as long as the pin 119 engagesthe pawl 115, so as to lock'the pin 116 of said pawl into one of therecesses of the disk 120, the disks 111, 113, 120, 122, and the gear 124will be locked together and driven by the gear 53. These elements are inthis way conjointly moved to register items, as controlled by thedevices before described, such movements being in tenths of arevolution. The gear 124, before referred to, meshes with the gear 131on the shaft 128, which gear 131 is mounted on a sleeve 129, theopposite end of said sleeve carrying the cam 130, located under the disk122 of the next adjacent train of higher order. Gam 130 carries aprojection 134, designed to engage in the notches of the disk 122 anddrive said disk, and consequently the next adjacent train of higherorder, the distance of one-tenth of a revolution for every completerevolution of the cam 130. In this manner cam 130 is driven by a trainof lower order, and whenever said train of lower order is moved acomplete revolution the notched disk 122 in the next adjacent train ofhigher order is moved one-tenth of a revolution, and the carrying fromone train to the next is thus effected. In order to arrest the train ofhigher order, or rather one part of it, so as to effect a movement ofthe disk 122 relative to the stationary part, the bell-crank lever,composed of the arms 136 and 139, is brought into action, the positionof said lever being controlled by the cam-groove in the cam. The arrowson the several disks and gears indicate their designed direction ofmovement in the-registration of items, and it will be seen that theprojection 134 is just leaving the notched disk 122, in which event theroller on member 136 of the bell-crank lever will ride in the concentricportion of the cam-groove for nine-tenths of a revolution or until theprojection 134 is again in position to engage and drive the disk 122.The cam shown in this ligure (23) is driven by the train of lower order,the gear 124 identilied with which is shown on the near end of the shaft108. Then the projection 134 is in position to engage the disk 122, thefluctuation in the cam-groove is so located that the next tenth of arevolution of the driving-train of lower order will cause the bell-crankleverA to rock, placing the pin 140 in the notches or recesses of thedisks 111 and 113. Inward movement of arm 139 accomplishes thefollowing: Disk 111 is arrested, and though at the time of its arrest itmay be receiving motion through the transmitting-gear 53 it will beremembered that there is a yielding connection between gears 55 and 53,which permits of the arrest of this disk 111, the motion being' absorbedby the spring' between gears 53 and 55, and upon the release of disk 111said disk is driven by the spring to the desired extent. However, wewill assume that for the purposes of this description disk 111 has beenarrested. The inward movement of pin 140 circumferentially displacesdisk 113 with respect to disk 111, so as to carry the pin 119 away fromthe projection 118 of the pawl 115, and thus the pawl lies passive, itspin 116 merely resting by its own weight, if the disks are in properposition, in one of the notches of the disk 120. At least disk 120 andits conjoined disk 122 are free to move when driven by the projection134. Projection 134 can only drive disk 122 coincidently with therocking or dipping movement of the bell-crank lever, and consequentlythe pawl 115 is unlocked only when disk 122 is receiving motion from thecam projection. The instant that the driving action between the camprojection 134 and the disk 122 has been completed the bell-crank leverleaves the fluctuation in the cam-groove and raises the pin 140 out ofthe disks 111 and 113, said disks now being restored to normal positionby their restoring-spring, before de- IIO scribed, so that the train islocked until the cam has again been rotated nine-tenths of a revolutionby the gear 124 identified with the train of lower order.

Should it happen that in restoring the wheels 66, which transmit theitem through the gears 55 53 110, &c., the gear 110 should betemporarily locked by its conjoined disk 111 being arrested by the pin140, (in the act of carrying from one train to the neXt,) it will beobvious that the spring 57, between and connecting the gears 55 53, Willyield and store up the movementimparted by gears 66 until the gears 53and 110 are released. Upon such release the spring will cause said gearsto rotate at such speed as to catch up to the positively-driven gear 55.

Tft/ring a total and @Zea/ring the 250ml/2671.` From what has been saidabove it is evident that the printing and indicating wheels are clearedor returned to zero when the item is placed in the totalizer. Repeatedoperations of the machine will cause the items to accumulate in thetotalizer, and in machines of this character it is desirable to operatethe printing and indicating wheels so that they will print and exhibitthe total of the items accumulated in the totalizer and also to clearthe totaliZer or return it to Zero. To effect this, I provide sleeves141 on the shaft 128, which sleeves have slots 142, through whichproject pins 143, fixed on the shaft 128. (See Fig. 4.) The cam-disks130 are provided with recesses 144 and pins 145. The pins 143 arenormally out of the paths of the pins 145, so that the cam-disks mayberotated without interruption. r1`he cam-disks and their associate parts,as well as the sleeves 141, are held against longitudinal movement bythe frameplates 104; but the shaft 128 is longitudinally movable, beingheld in its normal position, wherein the'pins 143 are out of the pathsof the pins 145, by means of a spring 147 bearing against a head 146.(See Figs. 2 and 5.)

148 indicates a crank-handle iixed to the opposite protruding end ofShaft 128, the inner end of the staff of which is provided with acam-surface 149, operating against a fixed projection 150. (See Fig 2a.)By this construction the shaft 128 is longitudinally displaced (or drawnto the right) as it is rotated, such longitudinal displacement locatingthe pins 143 in the paths of the pins 145 of all of the cam-disks whichhave been operated. The rotation of shaft 128 thus drives the camdisksand gears 131 and their respective trains on the shaft 108 backward, andthrough the connected intermediate gears rotating forwardly the totalwill be indicated on the disks 83 and will also appear in theprintingline o`n the wheels 80. It will be obvious that the shaft 128operates the respective type-wheels a distance corresponding to thebackward movement of each of the respective cam-disks 130. When thecam-disks reach their initial or home position, they are arrested.

In transmitting the total as contained in the totalizer through theseveral trains to the printing and indicating wheels means must beprovided for releasing the gears 77. Such is shown in Fig. 1, whereinthe frame-plate 104 of the totalizer is provided with a projection 162,which when the frame-plate is in a forward position strikes one memberof a bell-crank lever 160, pivoted at 161, whose other member isconnected by a link 163 to a projection 164 on the hub of the rock-arm8T. This rock-arm, it will be remembered, is fixed to the shaft 85,which carries the locking'- pawls 86.

Pawls 86, as before stated, are normally held against ratchets 84 by aspring 165, (see Fig. 5,) one end of which is attached to a pin 166 onshaft 85 and the opposite end to a pin 167 on plate 12. This springserves to hold the bell-crank lever againstthe projection 162, andconsequently assists the spring 151 in withdrawing the totalizer fromengagement with its driving-gears 53.

In taking a total the lever 98 is first depressed to engage theindicating and printing wheels with the totalizer, after which thecrank-handle 148 is operated to return the totalizer to Zero and placethe total in the indicating and printing disks. If the handle 148 isreturned home while the trains are in mesh, the total will be placedback in the totalizer and the indicating and printing wheels cleared. Ifit is desired to clear the totalizer, the handle 148 is operated torestore the totalizer to Zero while it is out of mesh with theindicating and printing wheels.
